Bill Nye Reveals Superman’s Secret To Shaving

In the third third official “Man of Steel” trailer, Superman has a beard and then all of a sudden he doesn’t. The big question here is: how did he shave it off? Gillette sets out to find an answer by probing the greatest minds in geekdom.

Bill Nye, for one, chooses to apply the Scientific Method to this problem, theorizing that Superman needn’t have used so complex a material as kryptonian, but rather he might’ve applied some sort of grinder that cuts the hair without damaging his skin.
